SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 437,852, dated October '7, 1890.

Application tiled February 25, 1889. Serial No. 301,124. (No model.)

T0 all whom, it may concern.-

Be it known that I, CHARLES J. CLARKE, a citizen of the United States, residing at Mount Crawford, in the county of Rockingham and State ot' Virginia, have invented certain new and useful Improvements in Combination Sash-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom panying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in combination sash-locks; and the objects ofthe invention are to produce a combination sashlock which will not only support and hold the lower or upper sash in any position in the frame, but also permit eitherone of the sashes to be tilted more or less for the purpose of ventilation, or for cleaning the win dow-panes,

or for painting the sashes; also to dispense.

with the ordinary windowstrips now employed, and instead to forni grooves in the sides of the frame in which shoes attached to the sash slide in raising and loweringr them; furthermore, to produce means by which the sash can be irmly held in an inclined position at any desired angle, and,nally, to produce a combination sash-lock of very simple construction and operation, that is not liable to get out of order, and can be easily attached to old as Well as new window frames and sash.

The invention consists in the construction of certain details and arrangement of parts, as will be more fully described hereinafter and specifically pointed out in the claims, reference being had to the accompanying drawings and the letters of reference marked thereon.

Like letters indicate similar parts in the different figures in the drawings, in which- Figure l represents a front elevation of a window-frame and sashes With the sash-locks attached. Fig. 2 is an irregular vertical crosssection on line x c of Fig. l. Fig. 3 is a horizontal section on line y y of Fig. 1. Fig. 4 is a detached view of a sash lock and shoe, on an enlarged scale, from its rear side Fig. 5

is a vertical section on line e zot' Fig. 4. Fig. 6 is a horizontal section on line o fu of Fig. 4.

In the drawings, A represents the windowframe, in which the sashes B are placed, having the sash-lock C and its shoe D attached in position. In the window-frame, on each side, are arranged the grooves a, in which the shoes freely slide up and down. To the upper ends of the shoes the cords and weights are secured, if desired, although not necessary. In the casing C of the lock is arranged the spring-bolt E, which is provided with a crank-arm e, having a pin e, which passes through the shoe D and enters into holes b, or depressions in the sides of the frame, and supports the sash at any desired height. The bolt E is actuated by a coil-spring f and is operated by a short handle on its end. Said handle may be detached, it' desired. A ratchet F is secured to the shoe and is let into a recess in the side of the casing of the lock, and is provided with notches d on its face, with which the end of another spring-bolt G engages. lVhen it is desired to tilt the windowsash, the spring-bolt G is iirst released from the notch with which it engages, and the said sash is then revolved on the pin e of the spring-bolt E to the required inclination, and the spring-bolt G is allowed to enter one of the other notches, and thus holds the sash in place. Said spring-bolt also serves to hold the sash vertical in the trame when in its ordinary position. A T-pieceton the springbolt G enters between the lugs d on the inside of the casing and prevents said bolt E from turning when actuated by the fingers.

A short pin 7L is arranged at the upper and lower sides of the window-sash, which enters into a hole or depression t' in the upper and lower ends of the window-frame and serves to hold it when closed, and also to prevent rattling.

On the edges ot the sash narrow pieces of rubber or equivalent material k, held by strips of tin or other sheet metall, are secured to serve as weather strips and prevent wind or dust from entering into the room.

The casing and shoes can be made of malleable or cast iron,- composition, or other suitable material, and, if desired, the casing may he made very ornamental, (bronzed or nickelplated.)

In the lock on the opposite side of the sash the ratchet F and spring-bolt G may be dispensed With.

Having thus described my invention, What I claim is- 1. A sash-lock attached to the Window-sash and provided with shoes arranged to slide in grooves in the Window frame and having spring-bolts, upon one of which the sash can be revolved, While the other bolt holds said sash in an inclined position by engaging with notches in theV ratchet F, as and for the purpose set forth. Y

2. In a sash-lock, the combination of the ratchet to which a shoe is attached and a spring-bolt. which passes through said ratchet on said shoe With a spring-bolt engaging with the notches on said ratchet and serving to hold the sash in an inclined position, all as and for the purpose set forth.

3. The combination of the casing C, provided with the lugs d', and the spring-bolt G, having T-piece z5, with the vshoe D and the ratchet e, and the spring-bolt E, having crankpin e, upon which the sash can be revolved, as and for the purpose specified.

In testimony whereof I afiiX my signature in presence of two Witnesses.

CHARLES J. CLARKE.
